VEHICLE-TIRE.

Speccation of Letters Patent.

Patented Mar. 8, 1921.

Application filed October 8, 1919. Serial No. 329,264.

To all w hom it may concern.' y

Be it known that I, Josnrn Fassino, a citizen ot the United States,residing at Bntalo, in the county ot' Erie and State of: Nev: York, haveinvented new and use tul improvements in vVehicle-filtres, ot which thefollowing is a specilication.

This intention relates to the class ot nonpuncturable cushion tireswhich are provided with a resilient core or liller in lieu ot the usualair-tube.

lts object is the improvement of the filler with a vienT of equallydistending and sup porting the tire casing on all sides and distributingthe load and strains as nearly as possible over all parts thereof, inorder-'to cause the tire to run smoothly as vvell as 1ncrease itsdurability. y

further object is the construction olf a iller ot this character whichcombines lightness with a high degree ot resilience.

ln the accompanying drawings:

Figure l. is a. fragmentary si( e elevation, partly in section, of avehicle Wheelequipped with the improvement. Fig'. Q is an enlarged crosssection ot the tire, on line Fig. l. Fig. 3 is a fragmentary perspectiveview of the iiller.

Similar characters of reference indicate corresponding parts in theSeveral views.

l0 indicates the customary shoe or casing oi the tire which forms nopart of my invention and may be of ordinary construction.

The core or iiller is oi substantially cruci- T'orm cross section withits radial Wings or flanges l1 extending continuously throughout thecircumference of the tire. Tivo o' these tlanges are disposed radiallyof the Wheel to distend and support the tire casing at the. centralportion of its tread, While the ether tivo extend laterally troni thebody of thD iller to distend the side portions oi the casing, Arrangedbetween adjacent flanges of the iiller are transverse Webs, blocks orpartitions l2 suitably spaced to distend and support those portions ofthe tire casing between the several flanges 11. rlhe edges of thesepartitions are curved to conform to the inner side ot' the casing, andin their preferred arrangement the partitions ot' one longitudinalseries are staggered with relation to those of the adjacent series; orin other Words, the partitions of one sector of the filler are arrangedopposite the spaces etween the partitions of the adjoining sectors, anddiagonally opposite partitions are in alinement with each othertransversely oi the liller.

By this construction and arrangement, a comparatively light and highlyresilient liller is produced which properly supports the tread and sideportions of the tire-cas ing uniformly throughout its circumference,this distributing the load and strains equally oyer the ,casing andincreasing the durability of the tire as a Whole. The partitions arearranged sufficiently close together to give the casing the necessarysupport at the tread to cause it to run smoothly or Withoutobjectionable vibration.

i desired, the filler may be Jfurther reduced in weight by providing itsflanges with longitudinal grooves 13 in their faces, and forming similargrooves 14 in the curved outer edges of the partitions. Thisconstruction also renders the filler more resilient.

T he entire filler may be molded in a single piece of rubber or othersuitable material having the necessary resilience.

I claim as my invention:

A resilient filler for tire casings, comprising a body portion ofcruel-form cross section, the four oppositely-extending longitudinalflanges of the filler being continuous and two ot Said flangesprojecting laterally in opposite directions to distend the side Walls ofthe tire casing, While the other two flanges are arranged radially inline With each other and extend in opposite directions from the centerof the filler to distend and support the tread portion of the tirecasing, and spaced transverse Webs bridging adjacent flanges, the outeredges of said flanges and said Webs being curved to conform to theinternal contour of the tirecasing, and the Webs of one sector .of thefiller being located opposite the spaces between the Webs of adjacentsectors.

JOSEPH PARRINO.
